Hi there, I am a 49 year old menopausal woman (I think!) who recently had a thyroidectomy. I currently am on Synthroid and other than the swollen eyes once month, I feel great. I get very swollen, sore eyes once a month, first one eye, then the next day usually the other. Once there was so much fluid build up behind my eye I had double vision. Even my ophthalmologist is stumped. Any ideas as to why? They were worse and I had other swelling in my body when I was on the birth control pill (used to control painful periods). It's strange that it is a cyclical thing. Anyone else experience this?
